London. May 10. 1852.

Dear Sir,

We are obliged by your letter about M. LeGray’s work on Photography, but before we can form any opinion on the subject we should wish to know what is the extent of the work, and what amount of engravings would be necessary. Perhaps you could let us see a copy of the first edition. In the mean time we will endeavour to see M^r Henneman

We are Dear Sir

Faithfully yours
